(Cl. 10S-236) 18 Claims. l

This application is a division of my prior application, Serial No. 543,709, now Patent No. 2,438,397, dated March 23, 1948.

This invention relates to improvements in locomotive tenders and particularly to water supplying and distributing means for such tenders.

In my aforesaid Patent No. 2,438,397 Il have shown a locomotive tender provided with rear, front and side water chambers, a Scoop for taking up water from a track-pan and delivering it to the rear water chamber, an expansionor surge chamber communicating with and adapted to receive air and water from Vthe rear water chamber, a divider operating in conjunction With the scoop and tender walls to spread the force of and to guide and deflect the Water from the scoop toward and distribute it to the water chambers, a top lling inlet communicating with the rear water chamber for filling the tender from a water column, said inlet having a normally closed, automatically closing closure member acting as a check valve, opening under the weight of water, when water is taken from a Water column, and closing under the action of its closing means and the pressure of the water in the rear water chamber when scooping, against the escape of water through the filling inlet and to allow the pressure in said chamber and in the expansion chamber to build up to facilitate the rapid distribution of the Water to water chambers, and air venting and water overflow means operating to allow controlled escape of air from the water and expansion chambers toV permit the tender to be lled to the desired maximum level and to permit of the dscharge of overflow water.

The present invention relates to the Water supplying means and coacting water distributing means referred to, and one of its objects is to provide novel and improved means particularly designed for cooperation with the scoop when scooping to effect the rapid distribution of the water to the Water chambers of the tender.

Another object of the invention is to so con'- struct the tender and the scoop that the water, forced through the scoopy and into the tank under high pressure of a fast-moving train, will be prevented from damaging the tank or other portions of the tender. i

Still another object of the invention is to provide a construction whereby the incoming water owing from the upper end of the scoop will be divided and spread in such manner that its force will be reduced and damage by water under high pressure eliminated.

Still another object of the invention is to provide a novel construction of means for preventingv undue and undesirable surging of the water in the water chambers While being iilled and while the tender is in motion.

Fig. l2 is a vertical transverse section on an enlarged scale through the tender taken substantially on line l2-l2 of Fig. 2, looking forwardly toward the slope sheet and rear bulkhead between the rear and side water chambers, portions of the scoop located below the tender being omitted.

In the accompany'ng drawings, the tender, which is indicated in general by the numeral l, is shown coupled to an engine 2 and is equipped with the usual trucks 3 carrying aXles 4 and wheels 5 for resting upon and rolling along the rails 6 of a track l. A scoop pan extends 1ongitudinally of the track between the rails and, at opposite sides of the track, are gutters '9 for catching water which may overflow when the tender is filled with water scooped from the pan 8.

The tender has the usual fuel space l0 and conveyor compartment l l, from which fuel is delivered to the rebox of the locomotive. There 3 has also been provided a rear water compartment I2 and a front water compartment or tank I3 which are connected with each other by side tanks or compartments I. Over the rear water compartment and back of the fuel space Il) is an expansion tankk l 5 which rises to. a` predeterm.Ilfd` level higher than the water compartments and;V

which has communication with the rear tank through drain openings IE and has its forward, portion I, which is of gradually reduced height, set off from its main portion= verlilrqlll'y` d'is;

and maintain anV even levell in the tanks. The

usual-,pipe Edis provided for-delivering. water from. the. tender to the boiler of the locomotive engine.

filling opening 2i is formed through the' topv wall 22 so that the water compartments or tanks be. filled from an overhead tank'at a station along the track by a spout thrust inwardly through the` filling opening. Through this -lling opening passes a funnel 2 3 which tapers downwardly to,v a small outlet atv its lower end and. has its upper portion projecting upwardly through the, lling, opening 2i and normally closed by a cover 26. This. cover is hinged at its iront end by hinges 25 so that it may be swung upwardly to open position, and, at its free rear edge, carries a, handle 2li for swinging the cover to raised position and a latch 2l. for engaging a keeper 281 and securing the cover closed. The reduced opening; alg-the lower end of the funnel is normally closed by agate 2Q having a hinge mounting 3B at its front edge so that it may swing vertically from raised or closed position against the lower end of;v the funnel, to lowered or open position. A bar or arm SiV extends from the hinged end of the gateV and arriesa weight 32 which urges the gate upwardly and normally holds it closed. When afilling spout of an overhead tank is thrust into. the funnel through. the upper end thereof, the force of water flowing from the spout will openV the gate and, when the spout is withdrawn,I the weight will return the gate to its closed posi tion. The funnel also serves as a manhole through which a workman may enter the waterl chamber I2 for inspecting, cleaning,l or repairing the same, and, in order that the workmanmay readily descend and climb out of the water cham# ber,l there h as been provided rungs 33 in the funnel and a ladder 34 which is attached to and extends downwardly from the funnel at a side thereof. It will thus be seen that the water chambers of the tender may be filled from an overhead tank of the type commonly provided at stations along a railway track.

In order that the water chamber may be lled from the Ywater pan 8 as the train moves along theV track,v there has'been provided a diagonally extending filling pipe 35 having a forwardly curved scoop 35 at its lower end. This scoop is pivotally mounted for swinging movement from raised or inoperative position, as shown in Fig. 6, to the, lowered position of Fig. 5, and is connected with a lifting arm 36 by a link 3l. Conventional mechanism is employed for operating the lifting armv to raise and lower the scoop and includes an operating valve 3,3 mounted at the front, of the tender, where it may be conveniently reached by an engineman. When the scoop is lowered, it extends into the water pan or trough, and since the tender is moving forwardly, water will pass upwardly through the pipe to the upper end thereof where it is discharged through the forwardly projecting.. elbow 3,9. and the discharge spoutorf nozzle dill, The nozzle all isi located in the space I5 between plates 42 with plate II at its rear and deecting irons 42 at its sides and extends under the rear slope sheet or plate 4I'v of fuel space IjG with the plate 22 cut away a-s' at 2:2" between' plates 42 and back to plate I sothat; water can flow unrestrictedly from the nozzle 40 downwardly and forwardly at an angle f parallel to and against the sloping plate or rear of the.v olfianilgaersv to such level. Thestream of incoming water discharged from the nozzle 40 strikes a divider d3 which is V-shaped in crossv section' andr tapers downwardly as well a forwardly.V Since the incoming tream of water is.

viz., 6,0 to 80 miles per hour or more. The water iillsv the rear chamber I2, the. side chambers I4, and the l, front chamber I3, and, in, orderthat tests mayA be made to determineif,V the water chambers need lling, there have been, provided a; number ofv test cocks located at. different.

vlevelsat oneside of the frontof the tender, where they may. be opened by. an engineman making thetest.

Qverflow pipes d6. 41.., 48 and 4S are disposed vertically atv their sides of the tender and have` their upper endsy communicating with the water chambers and the expansion chamberand their lower ends passing through, the bQttom of the tender and terminating,` in IlQZZles or spouts identied .by primed numerals cerlfesponding to the identifying numbers of the` pipes. Upper ends of. the pipes G6, 48 and 49 have reversed, downwardly extending elbows with.V inlell ends coi-nmunicating with the wateigchambers below their return bends, and the upper end. portions of; thel pipes 47 are bent laterallyf as shown at- 47a; extend atv an` upward incline towardl thek center of the expansion tank at its highest level; and terminating close; to, side walls of a channel 5l)`- formed across the top of the expansion chamber, the bottom wall of which forms a Walkway, so that trainman may easily cross the expansion tank when walking along the top of the` tender. The nozzles orv spouts at the lower ends of the pipes extend rearwardly at a downward incline, vas shown in Fig. 1, and, referring to Figs. 3 and 4;, it will be seen that theseV nozzles are also deilected to project outwardly at opposite sides o f the. #enden Therefore, when; Waterriows through the overflow pipes, it will be discharged rear- Wardly of the tender at a downward incline and outwardly from opposite sides of the tender so that it will be deposited in the gutters 9 at the sides ofthe track. In View of the fact that the transversely bent upper ends of the pipes have syphon-'breakers 5I and shield 5l therefor, the Water tanks or compartments will not be liable to be emptied. When water overflows from the tender, clue to overfllling of the compartments, or surging, it flows downwardly through the pipes and since it is discharged below the` tender, and

laterally therefrom into the gutters, formation of ice upon the tender will be prevented, and damaging overow from the top vents formerly used is eliminated.- It should also be noted that air which would normally be trapped in the chamber by inrushing water is discharged throughthe overflow pipes, thus eliminating back, pressure and allowing a greater amount of water to be scooped and eliminating damage to the tank by excessive pressure of air and water. When surging occurs, the water enters the expansion chamber and then flo-ws back into the main water chamber l2 at the back of the tender. In case any Water collects upon the top of the rear water chamber, it will drain therefrom through the drain pipes 52 located at rear corners of the tender near the pipes 4E.

The present invention has been designed for the purpose of allowing rapid filling of the tender with water when the tender is traveling at high train speeds, in such manner as to reduce waste of water while preventing bulging or disruption of walls or leak-straining of seams of walls or other damage to the tender, its running gear or to the trackway, or damage to a following ca-r or to cars traveling on other tracks and passing the tender while it is being lled by scoop operation, by which the water is being delivered in large volume and under great pressure liable to cause such damage unless the water is properly distributed throughout the water compartments immediately on delivery and unless dangerous pressures from air and excessive water supply are relieved. Excessive supply is particularly likely to happen at the higher speeds of from 60 to 80 or more miles per hour and to cause abnormally high pressures particularly if the pickup action of the scoop begns when the water compartments are from one-half to two-thirds full, and the apparatus must therefore function to rapidly distribute the water to the compartments and to give highly effective overflow and pressure relief actions in order to prevent damages of the character referred to.

The present invention has also been designed to facilitate the distribution of the water to the water chambers of the tender with greater facility and with a material saving of tme when the tender is lled from an overhead tank.

The speed of travel of high speed trains, those traveling at the rate of 45 to 60 miles per hour, and particularly those traveling at the rate of from 60 to 80 miles per hour or higher, as Well as the larger sized locomotives and tenders ern-v ployed in high speed trains and the amount of 'water carried and consumed, make it necessary to use means whereby the tender may be rapidly replenished with water without using a track pan of abnormal length and in order to prevent loss of timeVV so that a high speed schedule may be maintained. The use of a water scoop enables the operation of replenishing the tender to be carried out while-a train is traveling and without reductionfof speed. Ifomeet Aservice conditions,

however, it is necessary also to provide the tender with Va top filling inlet whereby it may be replenished with water from a water column at high pressure and in large volume to enable the tender to be quickly lled while standing at water stations. vIn the operation of lling from either a water column or water scoop, it is desirable or essential to provide means to permit the air pressure to escape sufficiently and without water Waste to effect quick distribution of the Water throughout the water chambers while permitting overflow of excess water when the tank is filled as well as to permit escape of air at the proper time to prevent dangerous over-pressure and to allow the tank to be lled to the desired maximum level. In order to secure these results when a scoop is used the top lling opening must be kept sealed against the discharge of air and water and against the forcible opening of its closure means under pressure while the pressure in the region thereof is building up to the desired degree to effect quick distribution of the water.

Prior to and during the stages of development of my invention, in tests conducted for the purposeY on the locomotive tenders of a well-known railroad, it was found that at the higher speeds named water began to be discharged from vents in the vertical wall immediately 'back of the fuel space within two or three seconds after the scoop had been'dropped into the pan and soon thereafter the water began to spray out from under the cistern cover with evidence of considerable pressure. The top of the tank back of the coal space was soon filled with water which then splashed over the side coping in waves, providing water in sufficient body to account for reported damages of the kind mentioned. Indeed, at the higher speeds the pressure was so great that the lock of the cistern cover was forced and the cover blown open, to release an on-rushing column of solid water discharging through the filling opening. It was also found that interior damages were caused by surging and excess pressure and damage to the wheel bearings and other parts of the running gear of the tender and to the track through displacement or the washing out of ballast.

These difliculties and disadvantages have been avoided and ocercome by my novel construction and combination of parts for effecting rapid distribution of the water by providing water dividing and air pressure reducing means to direct and cause proper distribution of the water to the water spaces of the tender, by the provision of means for sealing the top water inlet while scooping to allow the air pressure to escape and water to ll the tank to the maximum level, and by the provision of means for permitting excess water and air under pressure to escape at the proper time and discharging the excess water without damage to the tender running gear or to the trackway. The divider 43 is provided to check the force of the water flowing from the outlet 40 of the conductor 35 and to divide the stream for distribution to the compartments I2 and I4, whereby the full force of the pressure is prevented from .falling on any single wall and distribution of thewater is facilitated. The chamber I5 and its extension l5 are provided to receive the air forced upward in compartment` l2 as the water rises in the compartments so as to allow the water to rise to the intended maximum level, to build up an air pressure which assists in effecting distribution of the water, and to forman auxiliary reservoir or compartment dcris-s T in; whichrexcess water may be temporarily reeeivedand surging reduced. Thegatel isprovided to normally close. the funnel inlet. 23. and tofseal the same, against. escape of water and air during; scooping. and to allow the. air pressure to build up.V for the purposes described.. This. gate relieves the. cover. 2'5 from. the severefpressurev to which. it. otherwise would be. subjected in. scooping. and the liability of the cover being forced open. The. counterweight keeps the gate. normally closedandzthe gate ineifectacts as a check valve. opening under. the force of the. water. when it,l istaken from, a water column but closing against. the pressure inside. the tank whenlscoop.- ing.` The vents in the return bends at the tops ofl thesets. of vent. or overflow pipes of compara:- tiyely small diameter, which. arev arranged. to allow overflow of water atlspacedf intervals lon.- gitudinally of the tender from. the several com.- partments, arev provided to. allow escape of air as the water rises andare. necessary to prevent thev vent. pipes, the upper ends of some. of, which are below the4 level of the water in the surgetank l5 when full, from acting. as syphons to.. draw water from the tank after the scoop.. has been raised. During scooping the pipes allow air and excess water toV escape and the excess Water is discharged at the lower ends of the: pipes atsuch angles as to prevent damage-to the running; gear of the tender or to the ballast of the trackway, whereby disturbance or washing. away of the. ballast. is.. avoided..

By the above described construction and. ar` rangement. of parts water scooplng. at.. all. speeds is permitted,- and. permitted. atY ueryl high speeds without damage to. tender, trackway, or4 other cars. The. constructionV described, bythe use of the. check-valve, gate 29, also. permits ofthe.: use of.` a. top.. filling. inlet, for taking water from a water column, on a tender having a high! speed scoop, so.4 as.` to.- prevent. ordinary wasteY through the. inlet while-the4 scoop is beingusedor loss of water large. quantity due; to the. forcing-f. open of the inlet.v cover. andthe blowingV out of water through the inlet.

While the construction of means designed for ther stated purpose isfpreferred, it will',;of course, bezunderstoodlthat changes inthe form; proportion and,.arrangement-'of` parts, falling, within .the scope, of. the appendedclaims; may be madef'without. departing fromA the spiritvor sacricing any of the advantages of the invention.
